2.2. Safety Information

Before installation:

Read this manual completely and gather all information available on the unit. Make sure it is
fully understood. Check that your application does not exceed the safe operating
specifications for this unit.

This unit should only be installed by qualified personnel.

This unit should be built-in to an apparatus cabinet or similar, where access is restricted to
service personnel only.

The power supply wiring must be sufficiently fused, and if necessary, it must be possible to
disconnect it manually from all power supply. Ensure compliance to national installation
regulations.

This unit relies on convection cooling. Make sure that it is installed so that the ambient
temperature is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also see EN 45545-2 Mounting Notes [16] chapter.

WARNING - PREVENT ACCESS TO HAZARDOUS VOLTAGE

Before mounting, using or removing this unit: Prevent access to hazardous
voltage by disconnecting the unit from all power supply.

WARNING - HAZARDOUS VOLTAGE

Do not open the connected unit. Hazardous voltage may occur within this
unit when connected to power supply.

CAUTION - HOT SURFACE

Be aware of that the surface of this unit may become hot. When this unit
is operated at high temperatures, the external surface of the equipment
may exceed Touch Temperature Limit according to EN/IEC/UL 60950-1.

NOTICE - PROTECTIVE EARTHING CONDUCTOR

Before powering-up, a protective earthing conductor must be connected
to the protective earth terminal and have a cross-sectional area of at least

1.5 mm². Note that this unit can be connected to two different power
sources.

Viper 12A Series 5

NOTICE - REDUCE RISK OF FIRE

To reduce the risk of fire:

1. Use only No. 21 AWG or larger power cable

2. Use only No. 26 AWG or larger telecommunication line cord

NOTICE - CONNECT EXTERNAL FUSE

The unit has no internal fuse and should be connected via an external
fuse. The fuse should be calculated in accordance with the rated current.

2.3. Care Recommendations

Follow the care recommendations below to maintain full operation of unit and to fulfill the
warranty obligations:

• Do not attempt to dissassemble the unit. There are not any user serviceable parts
inside.

• Do not drop, knock or shake the unit. Rough handling above the specification may cause
damage to internal circuit boards.

• Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.

• Do not expose the unit to any kind of liquid (water, beverages, paint etc), unless all
connectors are connected or fitted with protective caps (delivered with the unit),
tightened to the specified torque. Connected cables must have the appropriate ingress
protection code.

• Do not use or store the unit in dusty or dirty areas, unless all connectors and the
ventilation membrane are sufficiently protected.

• Do not cover or bring mechanical force to the ventilation membrane on the back of the
unit.

If the unit is not working properly, contact the place of purchase, nearest Westermo
distributor office or Westermo Tech support.

2.4. Maintenance

2.6.2. FCC Part 15.105 Notice

This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residental
area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.

3. Product Description

3.1. Product Description

The Viper-12A series is a series of managed 12 port switches optimised for the needs of
the railway rolling stock market. Gbps ports cope with high bandwidth devices such as
access points and NVRs (Network Video Recorders).

The Viper is designed to withstand the tough environment on-board trains, exposing the
switch to constant vibration, extreme temperatures, humidity and a demanding electrical
environment.

A GORE-TEX® membrane prevents internal condensation. Threading integrated in chassis
provides for additional vibration resistance. High-level isolation between all interfaces
enables direct connectivity to vehicle auxiliary power and protects against overvoltage and
flashover. IP67 protection prevents ingress of water and dust. An overall optimised design
results in an extremely compact package in combination with very high MTBF for easy
integration and low lifecycle cost.

Thorough type testing at independent ISO/IEC 17025 and ILAC MRA certified labs,
accredited to a wide range of standards, show that the Viper series fulfilles EN 50155 and
other requirements. The state-of-the-art Westermo production facility ensures the quality
of each individual unit, e.g. through temperature cycling burn-in testing.

Meeting the requirements of the railcar market, the Viper is very well suited for
deployment in any other application with severe operating conditions and tough
environments, for instance in the mining industry.

3.2. Available Models

All switches are managed. Viper x12A is used when referring to both models 112A and
212A.
